Вы решили примеры не правильно,поэтому решаю сначала примеры,потом уравнения
ПРИНЦИП ОДИН И ТОТ ЖЕ. Надо смешанную дробь превратить в неправильную,а потом уже считать. Н-р,2  1/6=6*2+1=13/6
                                                 1  5/6=6*1+5=11/6
 Знаменатели не трогаем,а числители либо складываем,либо вычитаем(это уж как в примере)
2  1/6+1  5/6=13/6+11/6=24/6=4

2  1/6-1  56=136-116=26=13

z-4  4/7=2  5/7
z-32/7=19/7
z=19/7+32/7
z=51/7=7  2/7

5  6/13-с=3  11/13
71/13-с=50/13
с=71/13-50/13
с=21/13=1  8/13
